Synopsis
Moderate precipitation will continue to fall tonight into Thursday
as a low pressure system slowly sags through the region. A cold
front will follow on Friday for showers, gusty winds and cooler
temperatures that will last through the weekend and into Monday. A
return to warmer temperatures and drier conditions is expected next
week.

Discussion
With a late evening update I increased winds from the northern
moses lake area and up over the waterville plateau. There are a
few weather stations reporting winds of 20-30 mph with gusts to 45
mph. These winds are expected to decrease a little bit once the
rain gets going again overnight. I also slowed down the onset of
rain across the southeast portion of the region for tomorrow. The
00z GFS and NAM model guidance is consistent with less isentropic
ascent over this area with the jet pivoting more meridionally.

This will result in a narrower band of precipitation along the
cold front than previously thought. The southern to central
id panhandle will likely pick up the bulk of its precipitation
tomorrow evening. Svh

Aviation
06z tafs: a moist warm front with a modest 50 kt low level jet at
850 mbs will impact the region overnight into Thursday morning.

The low level jet will be focused primarily from around kdls to
khri through the columbia river gorge, across the upper columbia
basin and into the spokane coeur d'alene corridor. Low level wind
shear can be expected through this corridor with around 45 kt
winds possible down to between 1500 and 2000 ft agl at kmwh, kgeg,
ksff, kcoe and kpuw. The swath of rain has dwindled a bit through
the evening, but this will fill in again by Thursday morning
mainly northwest of a line from kpsc to kszt. The cold front will
take its time to push across with rain not expected to get into
kpuw and klws until late Thursday afternoon evening. Svh

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
